I run a 275 in front on a 9in rim...I realy dont like it.
The roads around here SUCK (98th worst in the nation), the crown of the roads tends to pull the thing like mad, the tires are also just a tad too wide and come ever so slightly past the front fender. My align. is also fubar (crappy shop, and roads lead to it going out fast...I did find a good local special shop I will be going to for now on though)
I would love to find some 265's but will prob. go with a 255 when I get new fronts.
